NOTE:
• The RADIUS scheme for voice RADIUS must be applied to the default domain named system.
• If a voice call is originated from an IP network to the voice gateway, the voice gateway does not
support the dialing of access numbers. The voice gateway supports only accounting to the PSTN
side, instead of authentication and authorization.

Troubleshooting voice RADIUS

Symptom 1
After the accounting function is enabled and the accounting method is set to start-ack or the
authentication/authorization function is enabled, the voice gateway fails to connect calls.
Follow the steps below to remove the fault:
1. Use the display voice access-number command to check that the current settings are
correct.
2. Check that the RADIUS server (CAMS) works correctly. For example, check that an IP service
module is installed on the CAMS, that the IP address of the voice gateway is allowed to access
to the CAMS, and that the CAMS and the voice gateway can communicate with each other by
using the ping command.
3. Check that the IP address, port number, and key of the RADIUS server on the RADIUS server
are consistent with those on the CAMS.
4. If the calling number authentication fails, check that an account is generated for the calling
number and that the account is bound to the calling number correctly.
5. If the card number/password authentication fails, check that the card number and password are
consistent with the ones generated on the CAMS.
6. If the authorization fails, check that call or access restriction is not set for the IP phone service
on the CAMS.
7. Check the log generated on the CAMS and remove the fault according to the errors.
Symptom 2
RADIUS authentication/authorization requests of voice users are always rejected.
Follow the steps below to remove the fault:
1. Follow the steps introduced in symptom 1 to see if the fault can be removed.
2. Check that the username, password, and service authorities of the user on the CAMS are
correct and that the authorities have taken effect.
3. Use the debugging voice radius all command to enable the debugging of the voice RADIUS
module and observe the message exchange in the entire authentication/authorization process.
Much of the debugging information gives reasons for voice call disconnection.
